[PATCH v1 0/3] PF: Add functions to save and restore VF LMEM and CCS data

[Lukasz Laguna]

State of VF LMEM and corresponding CCS metadata needs to be saved and
restored during migration of VM with attached dGPU VF. Add helpers that
allow it. We will start using them in upcoming patches.

Lukasz Laguna (3):
  drm/xe/migrate: Add function for raw copy of VRAM and CCS
  drm/xe/bo: Add trylock helper for buffer objects
  drm/xe/pf: Add functions to save and restore VF LMEM and CCS data
